STANCHION.

SPECIFICATION forming part of Letters Patent No. 770,203, dated September 13, 1904:.

Application filed March 5, 1904. Serial No. 196,696- (No model.)

To 00 whom, it may concern:

Be it known that I, THOMAS J. WALLACE, a citizen of the United States, residing at Albany, in the county of Orleans and State of Vermont, have invented a new and useful Stanchion, of which the following is a specification.

This invention relates to cattle-stanchions, and has for its object to simplify and improve the construction and produce a device of this character which when in open position will be locked from rotation and when in operative position will rotate to permit a greater freedom to the movements of the animals heads.

With these and other objects in view, which will appear as the nature of the invention is better understood, the, same consists in certain novel features of construction, as hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification and in which corresponding parts are denoted by like designating characters, is illustrated the preferred form of the embodiment of the invention capable of carrying the same into practical operation, it being understood that the invention is not necessarily limited thereto, as various changes in the shape, proportions, and general assemblage of the parts may be resorted to without departing from the principle of the invention or sacrificing any of its advantages, and the right is therefore reserved of making all the changes and modifications which fairly fall within the scope of the invention and the claims made therefor.

1n the drawings thus employed, Figure l is a perspective View of one of the improved stanchions in its closed or operative condition. Fig. 2 is a similar view with the improved device in its open or inoperative position. Fig. 3 is an enlarged sectional detail of the upper portion of the device.

The improved stanchion construction will be supported in a suitable framework, as represented, and erected in a stable, shed, or other suitable locality and comprising in its organization spaced base and head timbers 1O 11, connected at suitable intervals by vertical members 12 with the improved stanchions disposed in the panel-like openingsbetween them.

free end of the swinging bar 19 is a lockinglever 22, having a recess 23 in its longer end for engagement with the free end of the swinging bar 19 and with a lug 2 1 projecting from its shorter end above the upper line of the member 1 1 when the lever is'engaged with the swinging bar, the projecting lug providing means whereby the shorter end of the lever may be tilted to release the longer end from the swinging bar. The member 14: is also provided with a transverse stop 25 to limit the outward movement of the swinging bar. Attached to the head-timber is a U- shaped keeper 26, between whose spaced sides the shorter end of the lever 22 will pass when released from the swinging member 19.

In operating the device when it is desired to set. the stanchions to receive the cattle the shorter end of the locking-lever 22 is depressed by bearing down upon the lug 24, which elevates the longer end and releases the swinging bar 19, which falls outward by gravity until it rests against the end stop 25, while at the same time the longer end of the lockinglever has fallen by gravity and moved the shorter end into the space between the sides of the keeper member 26, thereby automatically locking the rotative stanchion within its supporting-framework. When the necks of the cattle are in position between the bars, the bar 19 is moved over into operative position, carrying the locking-lever with it and causing it to automatically engage therewith. This action releases the shorter end of the locking-lever from the keeper 26 and permits the stanchion to swing upon its pivots 16 17. By this simple means the stanchions are supported from rotation when not in use and in proper position to receive the cattle and are released automatically by the action of securing the cattle and permitted thereafter to rotate with the movements of the animals head. The animal will be secured in the stanchion, but under less restraint than with stationary stanchions.

The parts will preferably be of wood, with metal pivot members, and can be cheaply constructed and will not require the use of springs or other similar attachments, which are liable to get out of order.

Any required number of the improved stanchions may be employed in the supporting-framework and arranged in any desired relative position.

Having thus described the invention, what is claimed is 1. In a deviceof the class described, the combination with a frame, of a stanchion movably supported thereon and having a movable member, and means carried by the stanchion for engagement with the movable member to lock the same and capable of automatically moving into position for engagement with the frame to lock the stanchion against movement when said means is disengaged from the movable member and the stanchion is in alinement with the frame.

2. In a device of the class described, the combination with a frame, of a stanchion movably supported thereon and having a movable member, and a pivotal locking device carried by the stanchion for engagement with the movable member to lock the same and capable of gravitating into position for engagement with the frame to lock the stanchion against movement when released from the movable member of the stanchion and the stanchion is in alinement with the frame.

3. In a device of the class described, the combination with a frame, of a stanchion movably supported thereon and having a movable member, and a locking device pivoted at one side of its center upon the stanchion with one end formed for engagement with the movable member to lock the same, said locking device capable of gravitating into an upright position when disengaged from the movable member of thestanchion with its shorter end projected above the stanchion in position for engagement with the frame to lock the stanchion therewith when said stanchion is in alinement with the frame.

4. In a device of the class described, the combination with a frame, of a stanchion movably supported thereon and having a movable member, and a locking device pivoted at one side of its center upon the stanchion with its longer end formed for engagement with the movable member to lock thesanie and capable of gravitating into an upright position with its shorter end projected above the top of the stanchion into position for engagement with the frame to lock the stanchion when the latter is in alinement with said frame.

5. In a device of the class described, the combination with a frame, of a stanchion including a slotted head and a base rotatably connected to the frame, a stationary bar connecting said members, a movable bar pivoted to the base member with its upper end working in a slot in the head member, a locking device pivoted intermediately within the slot of the head member with one end heavier than the other and formed for engagement with the pivotal member of the stanchion in a transverse disposition to lock said member and capable of gravitating into an upright position when released from said member, and a keeper carried by the upper portion of the frame in position to receive the upper end of the locking device when released from the pivotal stanchion member to lock the stanchion against rotation upon the frame.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the -presence of two witnesses.

THOMAS J. WALLACE.
